The period from the loss of the Space Shuttle Columbia in February 2003 to resumption of Space Shuttle flights in July 2005 has presented significant challenges to International Space Station (ISS) maintenance operations. NASA has revised its support strategy and undertaken maintenance activities that have significantly expanded the envelope of the ISS maintenance concept. This experience has enhanced confidence in the ability to continue to support ISS in the period following the permanent retirement of the Space Shuttle fleet in 2010. These experiences and capabilities acquired will serve as the foundation for the maintenance strategy that will be employed in support of future missions such as missions to the Moon and to more distant destinations such as Mars. Because of the limitation on launching external, unpressurized cargo, especially very large items after 2010 to the ISS, an effort will be made to preposition as much external hardware as possible at ISS before Shuttle retirement. It is expected that by 2014 the external spares inventory may be fully expended and therefore no external maintenance could be performed after that point. Internal maintenance is faced with different but equally significant challenges. The ISS program is constrained by the number of spares available and a limited capacity of return of failed units for refurbishment at depot facilities. Therefore expansion of maintenance and repair capabilities that allow the preservation of spares is highly attractive. Experiences acquired during the recent Shuttle stand-down has shown that it is possible to perform maintenance that was previously not considered. This experience has stimulated consideration of ways to further expand the maintenance capability envelope and to make these types of repairs more standard. The new capabilities are very similar to those that will be required to enable future human exploration missions.
